The concern for the role of emotion in argumentative encounters has rested upon the concept of emotion as arguments, emotions to obtain the adherence of the audience and reflect the virtues of a good arguer. In this paper, we focus on understanding emotion and argumentation based on cognitive approaches that identify the relationship between the two elements, to propose the use of emotion regulation strategies in deliberative dialogue. Bearing in mind that the intensity of emotional responses may, in some cases, (...) hamper one’s capacity to solve problems during a practical argument, we suggest that the use of emotion regulation strategies may favor deliberative dialogue, leading to more adaptive emotional responses and, in turn, better argumentative encounters, rendering decision-making more efficient. This article conceptualizes argumentation, revealing the historical path of emotion in studies on argumentation. It presents the concepts of emotion and emotion regulation, followed by the function of emotion regulation in argumentative encounters, illustrating this in two different situations. We conclude with the contribution made by the use of strategies for emotion regulation during deliberative dialogue. (shrink)
